CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application claims the benefit to and is a continuation ofU.S. Non-provisional patent application Ser. No. 15/011,377, filed Jan.29, 2016, which claims the benefit of U.S. Provisional PatentApplication No. 62/110,449, filed Jan. 30, 2015, each of which isincorporated by reference herein in its entirety.

FIELD OF THE INVENTION

The present invention relates to crystalline forms of4-(5-Chloro-2-isopropylaminopyridin-4-yl)-1H-pyrrole-2-carboxylic acid[1-(3-chlorophenyl)-2-hydroxyethyl]amide, which is useful as aninhibitor of ERK protein kinase.

BACKGROUND OF THE INVENTION

Mitogen-activated protein kinase (MAPK) pathways mediate signals whichcontrol diverse cellular processes including growth, differentiation,migration, proliferation and apoptosis. One MAPK pathway, theextracellular signal-regulated kinase (ERK) signaling pathway, is oftenfound to be up-regulated in tumors. Pathway members, therefore,represent attractive blockade targets in the development of cancertherapies (Kohno and Pouyssegur, 2006). For example, U.S. Pat. No.7,354,939 B2 discloses, inter alia, compounds effective as inhibitors ofERK protein kinase. One of these compounds,4-(5-Chloro-2-isopropylaminopyridin-4-yl)-1H-pyrrole-2-carboxylic acid[1-(3-chlorophenyl)-2-hydroxyethyl]amide, is a compound according toformula (I):

Pharmaceutical compositions are often formulated with a crystallinesolid of the active pharmaceutical ingredient (API). The specificcrystalline form of the API can have significant effects on propertiessuch as stability and solubility/bioavailability. Instability andsolubility characteristics can limit the ability to formulate acomposition with an adequate shelf life or to effectively deliver adesired amount of a drug over a given time frame (Peterson et al.,2006).

There exists an unmet need for crystalline forms of4-(5-Chloro-2-isopropylaminopyridin-4-yl)-1H-pyrrole-2-carboxylic acid[1-(3-chlorophenyl)-2-hydroxyethyl]amide which exhibit improvedproperties for formulation of pharmaceutical compositions. The presentapplication is directed to meeting this and other needs.

The term “solid form” is often used to refer to a class or type ofsolid-state material. One kind of solid form is a “polymorph” whichrefers to two or more compounds having the same chemical formula butdiffering in solid-state structure. Salts may be polymorphic. Whenpolymorphs are elements, they are termed allotropes. Carbon possessesthe well-known allotropes of graphite, diamond, andbuckminsterfullerene. Polymorphs of molecular compounds, such as activepharmaceutical ingredients (“APIs”), are often prepared and studied inorder to identify compounds meeting scientific or commercial needsincluding, but not limited to, improved solubility, dissolution rate,hygroscopicity, and stability.

Other solid forms include solvates and hydrates of compounds includingsalts. A solvate is a compound wherein a solvent molecule is present inthe crystal structure together with another compound, such as an API.When the solvent is water, the solvent is termed a hydrate. Solvates andhydrates may be stoichiometric or non-stoichiometric. A monohydrate isthe term used when there is one water molecule, stoichiometrically, withrespect to, for example, an API, in the unit cell.

In order to identify the presence of a particular solid form, one ofordinary skill typically uses a suitable analytical technique to collectdata on the form for analysis. For example, chemical identity of solidforms can often be determined with solution-state techniques such as¹³C-NMR or ¹H-NMR spectroscopy and such techniques may also be valuablein determining the stoichiometry and presence of “guests” such as wateror solvent in a hydrate or solvate, respectively. These spectroscopictechniques may also be used to distinguish, for example, solid formswithout water or solvent in the unit cell (often referred to as“anhydrates”), from hydrates or solvates.

Solution-state analytical techniques do not provide information aboutthe solid state as a substance and thus, for example, solid-statetechniques may be used to distinguish among solid forms such asanhydrates. Examples of solid-state techniques which may be used toanalyze and characterize solid forms, including anhydrates and hydrates,include single crystal X-ray diffraction, X-ray powder diffraction(“XRPD”), solid-state ¹³C-NMR, Infrared (“IR”) spectroscopy, includingFourier Transform Infrared (FT-IR) spectroscopy, Raman spectroscopy, andthermal techniques such as Differential Scanning calorimetry (DSC),melting point, and hot stage microscopy.

Polymorphs are a subset of crystalline forms that share the samechemical structure but differ in how the molecules are packed in asolid. When attempting to distinguish polymorphs based on analyticaldata, one looks for data which characterize the form. For example, whenthere are two polymorphs of a compound (e.g., Form I and Form II), onecan use X-ray powder diffraction peaks to characterize the forms whenone finds a peak in a Form I pattern at angles where no such peak ispresent in the Form II pattern. In such a case, that single peak forForm I distinguishes it from Form II and may further act to characterizeForm I. When more forms are present, then the same analysis is also donefor the other polymorphs. Thus, to characterize Form I against the otherpolymorphs, one would look for peaks in Form I at angles where suchpeaks are not present in the X-ray powder diffraction patterns of theother polymorphs. The collection of peaks, or indeed a single peak,which distinguishes Form I from the other known polymorphs is acollection of peaks which may be used to characterize Form I. If, forexample, two peaks characterize a polymorph then those two peaks can beused to identify the presence of that polymorph and hence characterizethe polymorph. Those of ordinary skill in the art will recognize thatthere are often multiple ways, including multiple ways using the sameanalytical technique, to characterize polymorphic polymorphs. Forexample, one may find that three X-ray powder diffraction peakscharacterize a polymorph. Additional peaks could also be used, but arenot necessary, to characterize the polymorph up to and including anentire diffraction pattern. Although all the peaks within an entirediffractogram may be used to characterize a crystalline form, one mayinstead, and typically does as disclosed herein, use a subset of thatdata to characterize such a crystalline form depending on thecircumstances.

For example, as used herein, “characteristic peaks” are a subset ofobserved peaks and are used to differentiate one crystalline polymorphfrom another crystalline polymorph. Characteristic peaks are determinedby evaluating which observed peaks, if any, are present in onecrystalline polymorph of a compound against all other known crystallinepolymorphs of that compound to within ±0.2° 2θ.

When analyzing data to distinguish an anhydrate from a hydrate, forexample, one can rely on the fact that the two solid forms havedifferent chemical structures—one having water in the unit cell and theother not. Thus, this feature alone may be used to distinguish the formsof the compound and it may not be necessary to identify peaks in theanhydrate, for example, which are not present in the hydrate or viceversa.

X-ray powder diffraction patterns are some of the most commonly usedsolid-state analytical techniques used to characterize solid forms. AnX-ray powder diffraction pattern is an x-y graph with the diffractionangle, 2θ (°), on the x-axis and intensity on the y-axis. The peakswithin this plot may be used to characterize a crystalline solid form.The data is often represented by the position of the peaks on the x-axisrather than the intensity of peaks on the y-axis because peak intensitycan be particularly sensitive to sample orientation (see PharmaceuticalAnalysis, Lee & Web, pp. 255-257 (2003)). Thus, intensity is nottypically used by those skilled in the art to characterize solid forms.

As with any data measurement, there is variability in X-ray powderdiffraction data. In addition to the variability in peak intensity,there is also variability in the position of peaks on the x-axis. Thisvariability can, however, typically be accounted for when reporting thepositions of peaks for purposes of characterization. Such variability inthe position of peaks along the x-axis derives from several sources. Onecomes from sample preparation. Samples of the same crystalline material,prepared under different conditions may yield slightly differentdiffractograms. Factors such as particle size, moisture content, solventcontent, and orientation may all affect how a sample diffracts X-rays.Another source of variability comes from instrument parameters.Different X-ray instruments operate using different parameters and thesemay lead to slightly different diffraction patterns from the samecrystalline solid form. Likewise, different software packages processX-ray data differently and this also leads to variability. These andother sources of variability are known to those of ordinary skill in thepharmaceutical arts.

Due to such sources of variability, it is common to recite X-raydiffraction peaks using the word “about” prior to the peak value indegrees (2θ) (sometimes expressed herein as “2θ-reflections (°)”), whichpresents the data to within 0.1 or 0.2° (2θ) of the stated peak valuedepending on the circumstances. The X-ray powder diffraction datacorresponding to the solid forms of the present invention were collectedon instruments which were routinely calibrated and operated by skilledscientists. In the present invention, XRPD values are preferablyobtained using Cu Kα X-ray radiation according to the method describedin Example 1. Accordingly, the variability associated with these datawould be expected to be closer to ±0.1° 2θ than to ±0.2° 2θ and indeedlikely less than 0.1 with the instruments used herein. However, to takeinto account that instruments used elsewhere by those of ordinary skillin the art may not be so maintained, for example, all X-ray powderdiffraction peaks cited herein have been reported with a variability onthe order of ±0.2° 2θ and are intended to be reported with such avariability whenever disclosed herein and are reported in thespecification to one significant figure after the decimal even thoughanalytical output may suggest higher precision on its face.

Single-crystal X-ray diffraction provides three-dimensional structuralinformation about the positions of atoms and bonds in a crystal. It isnot always possible or feasible, however, to obtain such a structurefrom a crystal, due to, for example, insufficient crystal size ordifficulty in preparing crystals of sufficient quality forsingle-crystal X-ray diffraction.

X-ray powder diffraction data may also be used, in some circumstances,to determine the crystallographic unit cell of the crystallinestructure. The method by which this is done is called “indexing.”Indexing is the process of determining the size and shape of thecrystallographic unit cell consistent with the peak positions in asuitable X-ray powder diffraction pattern. Indexing provides solutionsfor the three unit cell lengths (a, b, c), three unit cell angles (α, β,γ), and three Miller index labels (h, k, l) for each peak. The lengthsare typically reported in Angstrom units and the angles in degree units.The Miller index labels are unitless integers. Successful indexingindicates that the sample is composed of one crystalline phase and istherefore not a mixture of crystalline phases.

IR spectroscopy, particularly FT-IR, is another technique that may beused to characterize solid forms together with or separately from X-raypowder diffraction. In an IR spectrum, absorbed light is plotted on thex-axis of a graph in the units of “wavenumber” (cm⁻¹), with intensity onthe y-axis. Variation in the position of IR peaks also exists and may bedue to sample conditions as well as data collection and processing. Thetypical variability in IR spectra reported herein is on the order ofplus or minus 2.0 cm⁻¹. Thus, the use of the word “about” whenreferencing IR peaks is meant to include this variability and all IRpeaks disclosed herein are intended to be reported with suchvariability.

Thermal methods are another typical technique to characterize solidforms. Different polymorphs of the same compound often melt at differenttemperatures. Thus, the melting point of a polymorph, as measured bymethods such as capillary melting point, DSC, and hot stage microscopy,alone or in combination with techniques such as X-ray powderdiffraction, IR spectroscopy, including FT-IR, or both, may be used tocharacterize polymorphs or other solid forms.

As with any analytical technique, melting point determinations are alsosubject to variability. Common sources of variability, in addition toinstrumental variability, are due to colligative properties such as thepresence of other solid forms or other impurities within a sample whosemelting point is being measured.

The pharmaceutical compositions of the present invention for rectal orvaginal administration may be presented as a suppository, which may beprepared by mixing one or more active ingredient(s) with one or moresuitable nonirritating diluents or carriers which are solid at roomtemperature, but liquid at body temperature and, therefore, will melt inthe rectum or vaginal cavity and release the active compound. Thepharmaceutical compositions of the present invention which are suitablefor vaginal administration also include pessaries, tampons, creams,gels, pastes, foams or spray formulations containing suchpharmaceutically-acceptable diluents or carriers as are known in the artto be appropriate.

Dosage forms for the topical or transdermal administration includepowders, sprays, ointments, pastes, creams, lotions, gels, solutions,patches, drops and inhalants. The active agent(s)/compound(s), includingthe solid forms of the present invention, may be mixed under sterileconditions with a suitable pharmaceutically-acceptable diluent orcarrier. The ointments, pastes, creams and gels may contain excipients.Powders and sprays may contain excipients and propellants.

The pharmaceutical compositions of the present invention suitable forparenteral administrations may comprise one or more agent(s)/compound(s)in combination with one or more pharmaceutically-acceptable sterileisotonic aqueous or non-aqueous solutions, dispersions, suspensions oremulsions, or sterile powders which may be reconstituted into sterileinjectable solutions or dispersions just prior to use, which may containsuitable antioxidants, buffers, solutes which render the formulationisotonic with the blood of the intended recipient, or suspending orthickening agents. Proper fluidity can be maintained, for example, bythe use of coating materials, by the maintenance of the requiredparticle size in the case of dispersions, and by the use of surfactants.These pharmaceutical compositions may also contain suitable adjuvants,such as wetting agents, emulsifying agents and dispersing agents. It mayalso be desirable to include isotonic agents. In addition, prolongedabsorption of the injectable pharmaceutical form may be brought about bythe inclusion of agents which delay absorption.

In some cases, in order to prolong the effect of a drug (e.g.,pharmaceutical formulation), it is desirable to slow its absorption fromsubcutaneous or intramuscular injection. This may be accomplished by theuse of a liquid suspension of crystalline or amorphous material havingpoor water solubility.

The rate of absorption of the active agent/drug, including the solidforms of the present invention, then depends upon its rate ofdissolution which, in turn, may depend upon crystal size and crystallineform. Alternatively, delayed absorption of a parenterally-administeredagent/drug may be accomplished by dissolving or suspending the activeagent/drug in an oil vehicle. Injectable depot forms may be made byforming microencapsule matrices of the active ingredient inbiodegradable polymers. Depending on the ratio of the active ingredientto polymer, and the nature of the particular polymer employed, the rateof active ingredient release can be controlled. Depot injectableformulations are also prepared by entrapping the drug in liposomes ormicroemulsions which are compatible with body tissue. The injectablematerials can be sterilized for example, by filtration through abacterial-retaining filter.

The formulations may be present in unit-dose or multi-dose sealedcontainers, for example, ampules and vials, and may be stored in alyophilized condition requiring only the addition of the sterile liquiddiluent or carrier, for example water for injection, immediately priorto use. Extemporaneous injection solutions and suspensions may beprepared from sterile powders, granules and tablets of the typedescribed above.

The following examples are provided to further illustrate the compounds,compositions and methods of the present invention. These examples areillustrative only and are not intended to limit the scope of theinvention in any way.

EXAMPLES Example 1 Experimental Methods X-Ray Powder Diffraction (XRPD)

Transmission mode XRPD patterns were collected using an incident beam ofCu radiation produced using a fine-focus source. An elliptically gradedmultilayer mirror was used to focus Cu Kα X-ray radiation through thespecimen and onto the detector. Prior to the analysis, a siliconspecimen (NIST SRM 640d) was analyzed to verify that the observedposition of the Si 111 peak was consistent with the NIST-certifiedposition. A specimen of the sample was sandwiched between 3-μm-thickfilms and analyzed in transmission geometry. A beam-stop, shortantiscatter extension, and antiscatter knife edge were used to minimizethe background generated by air. Soller slits for the incident anddiffracted beams were used to minimize broadening from axial divergence.Diffraction patterns were collected using a scanning position-sensitivedetector located 240 mm from the specimen. Preferred orientation andparticle static effects were not assessed.

Reflection mode XRPD patterns were collected using an incident beam ofCu Kα radiation produced using a fine-focus source and a nickel filter.The diffractometer was configured using the symmetric Bragg-Brentanogeometry. Prior to the analysis, a silicon specimen (NIST SRM 640d) wasanalyzed to verify that the observed position of the Si 111 peak wasconsistent with the NIST-certified position. A specimen of the samplewas prepared as a thin, circular layer centered on a siliconzero-background substrate. Antiscatter slits (SS) were used to minimizethe background generated by air. Soller slits for the incident anddiffracted beams were used to minimize broadening from axial divergence.Diffraction patterns were collected using a scanning position-sensitivedetector located 240 mm from the sample. Preferred orientation andparticle static effects were not assessed.

Under most circumstances, peaks within the range of up to about 30° 2θwere selected. The location of the peaks along the x-axis (° 2θ) wererounded to one significant figure after the decimal point. Peak positionvariabilities are given to within ±0.2° 2θ based upon recommendationsoutlined in the USP discussion of variability in X-ray powderdiffraction. The accuracy and precision associated with any particularmeasurement was not determined. Moreover, third party measurements onindependently prepared samples on different instruments may lead tovariability which is greater than ±0.2° 2θ. Per USP guidelines, variablehydrates and solvates may display peak variances greater than 0.2° 2θand therefore peak variances of 0.2° 2θ are not applicable to thesematerials. For d-space listings, the wavelength used to calculated-spacings was 1.5405929 Å, the Cu-Kα1 wavelength. Variabilityassociated with d-spacing estimates was calculated from the USPrecommendation, at each d-spacing, and provided in the respective datatables.

Fourier Transform Infrared (FT-IR) spectroscopy

FT-IR spectra were acquired using a Fourier transform infraredspectrophotometer equipped with a mid/far IR source, an extended rangepotassium bromide (KBr) beamsplitter, and a deuterated triglycinesulfate (DTGS) detector. Wavelength verification was performed usingNIST SRM 1921b (polystyrene). An attenuated total reflectance (ATR)accessory with a germanium (Ge) crystal was used for data acquisition.256 co-added scans were collected at a spectral resolution of 2 cm⁻¹. Abackground data set was acquired with a clean Ge crystal. A Log 1/R(R=reflectance) spectrum was obtained by taking a ratio of these twodata sets against each other. Peak picking was performed using anabsolute threshold near the baseline and a sensitivity of 75.

Differential Scanning Calorimetry (DSC)

DSC analysis was performed using a differential scanning calorimeter.Temperature calibration was performed using NIST-traceable indium metal.The sample was placed into an aluminum DSC pan, covered with a lid, andthe weight was accurately recorded. A weighed aluminum T0HSMP panconfigured as the sample pan was placed on the reference side of thecell. Reported temperatures are rounded to 1 degree unless specifiedotherwise.

Raman Spectroscopy

Raman spectroscopy was performed using a dispersive RamanRXN3 (KaiserOptical Systems Inc., Ann Arbor, Mich.) for in-situ reaction monitoring.The RamanRXN3 system uses an excitation wavelength of 785 nm, with anexternal cavity-stabilized, diode laser. All spectra were acquired usinga ¼″ immersion optics probe with approximately 103 mW of laser power atthe tip of the probe. The spectra were collected using an exposure timeof 5 up to 15 seconds and with 5 spectrum accumulations. Wavelength andlaser wavelength calibration were performed using an internal neonstandard, and diamond Raman shift standard, respectively. The intensitycalibration was performed using a Kaiser Raman calibration accessory(Kaiser Optical Systems Inc., Ann Arbor, Mich.).

Example 3A Preparation of4-(5-Chloro-2-isopropylaminopyridin-4-yl)-1H-pyrrole-2-carboxylic acid[1-(3-chlorophenyl)-2-hydroxyethyl]amide Form C

4-(5-Chloro-2-isopropylaminopyridin-4-yl)-1H-pyrrole-2-carboxylic acid[1-(3-chlorophenyl)-2-hydroxyethyl]amide Form C was prepared from4-(5-Chloro-2-isopropylaminopyridin-4-yl)-1H-pyrrole-2-carboxylic acid[1-(3-chlorophenyl)-2-hydroxyethyl]amide free base as follows.ASYM-111935 (10.4 kg) was added to a stirred mixture of anhydrousethanol (73.9 kg), methanol (4.1 kg) and isopropanol (4.1 kg). Themixture was heated to 70-75° C. and stirred until all the solidsdissolved. Anhydrous HCl (37 wt %, 1.1 eq) in a mixture ofethanol/methanol/isopropanol (90:5:5) was added and the mixturemaintained at 70-75° C. for 2 hours after the addition was completed.The mixture was then cooled to 15-25° C. at a rate of 5-15° C. per hourand stirred at this temperature until the desired polymorphic purity wasreached. The end point of the crystallization/polymorph conversion wasdetermined by the absence of an XRPD peak at about 10.5° 2θ in threesuccessive samples.

The mixture was then filtered and washed successively with apre-prepared solution of anhydrous ethanol (14.8 kg), methanol (0.8 kg)and isopropanol (0.8 kg), followed by MTBE (2×21 kg). Avoidance of delayin the washing of the filter cake is preferable because the polymorphmay be unstable in the wet filter cake in the presence of reagentalcohol and improved stability was observed after the MTBE wash has beenperformed. The wet filter cake was then dried in a heated filter funnelor a tray drier at 40-50° C. until dry. Typical yields were about85-90%.
